Application filed April 22,

To all whom it may concern:

Be it known that l, FRANK LA BELLE, citizen of the United States, residing at Seattle, in the county of King and State of lVashington. have invented a certain new and useful Improvement in Belt-Splices, of which the following is a specification.

My invention relates to improvements in splices tor belts that are adapted to be embodied in belts made of a plurality of layers or plies of suitable material, and the object 01 my improvement is to provide a practical and eflicient form of splice that may be quickly and easily made to splice such belts as are made of a plurality of layers or plies of material without greatly increasing the thickness of a belt within the spliced portion and which splice shall not present an exposed end tobe torn or loosened by its engagement with revolving pulleys.

l attain this object by a form of splice illustrated in the accompanying drawings, wherein Figure 1, is a view in side elevation of the two ends of a tour ply belt formed to adaptthem to be joined to make a splice embodying my invention; Fig. 2, is a view in side elevation of the same after the two lower plies are spliced; Fig. 8 is a plan view of the same belt end shown in Fig. 2; Fig. 4:, is a plan view of one side of the spliced portion of the belt after its completion, a portion of the top ply of the belt being broken away to show other portions; and Fig. 5, is a sectional view on the line w, 00 of Fig. t.

Like reference numerals indicate like parts throughout. the several views.

Referring to the drawings, two opposed belt ends of a tour ply belt, are shown, one end as composed of plies 6, 7, 8 and 9, and the other end as composed of plies 10, 11, 12 and 13. The longer upper and longer lower plies 6 and 10 respectively each have their ends tapered to a point and each is so cut away on each side near its end as to leave two shoulders 1e, 14, thus to form the shape of a barbed arrow-head, as shown in Figs. 3 and a, while the lower ply 9 and the upper ply 13 are each provided with a transversely slotted hole 15 at a short distance from its end, as shown in Fig. 3, within which holes Specification of Letters Patent.

7 is folded downwardly to fit within the V shaped notch in the end of the ply 12. The ply 18 containing the slotted hole 15 is then turned down on the ply 12, the ply 6 is then turned oown on said ply 13 and the notched end of the ply 6 is folded and thrust into the slotted hole 15 until the shoulders 14, 14 shall have passed through the hole The end of the ply 6 is then flattened out as illustrated in Fig. 5, the narrowest portion of the end 6 fitting the slotted hole 15, while the shoulders 14, l l serve to prevent the ply 3 from being withdrawn from the slotted hole 15 and the belt ends from being pulled apart. The lower plies 8, 11, 9 and 10 are then associated in a manner similar to that of the corresponding upper plies and the several plies embodied in the splice are then securely cemented together to complete the splice.

()bviously my invention is not limited in its scope to a four ply belt but may be advantageously embodied in any belt that is made up of a plurality of plies, the plies interposed between the two outside plies having their ends so formed that the wedge shaped end of the one shall fit the V shaped end of the corresponding opposed ply, said plies varying in length so that no two joined ends shall register with any other two like joined ends when the splice is completed.

What I claim is:

In a belt composed of a plurality of plies of material, a belt splice wherein one end portion of the outer ply of each side of said belt is shaped substantially like a barbed arrow-head while the other end portion of such outer ply of each side of said belt is provided with a transverse slot adapted to re eeive and securely hold the corresponding barbed arrow-head shaped end portion to unite said end portions, the ends of each of In Witness whereof, I, hereunto subscribe the interior plies being formed one in shape my name this 31st day of March A.
